A senior congressional reporter for Politico tweeted on Wednesday evening that he did not believe Sen. Kirsten Gillibrand's claims that she had been subjected to sexist remarks and actions from her congressional colleagues.

John Bresnahan is a longstanding and respected congressional reporter for Politico. But he responded skeptically after Gillibrand recalled several sexist encounters in a yet-to-be-released interview with People magazine about her forthcoming book. The New York Post reported on portions of the People interview Wednesday.

Bresnahan weighed in when Huffington Post associate politics editor (and former TPMer) Igor Bobic tweeted out a headline about Gillibrand's reported tales of being told not to get "porky" and also told not "to lose too much weight... I like my girls chubby" by congressional colleagues.

It is not clear if there was a specific story that Bresnahan doesn't believe or why he was skeptical. But Bresnahan reaffirmed in a follow-up tweet that he didn't believe Gillibrand's version of events.
